Sacrario di Cristo Re overlooks Messina from a hill that once was the site of a Roman acropolis and later a Norman castle dedicated to Richard the Lionheart. The neo-baroque structure was built in 1937 as a memorial to WWI casualties. It contains the bodies of about 1,000 soldiers. Next to the church is this 130 ton bronze bell. It was cast from melted down enemy cannons and it sits on a tower from the ruins of the Roccaguelfonia fortress.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
